Archaeological research of the Neolithic period in Southwest Asia depicts socio-cultural developments and proto-urban villages, resulting from an intensifying agro-economy, emerging simultaneously during the first 5,000 years of the Holocene (11,000 to 6,000 bp). Kholetria-Ortos…

The environmental aspects of Neolithic Boiotia and the Neolithic technologies that were developed in this area are presented and evaluated in this dissertation. Chaironeia has been used as a pilot-site and the excavator of the site, H. Tzavella-Evjen, has kindly permitted me to …
Coccoliths, the minute calcareous plates produced by photosynthetic algae, were studied in high-resolution, AMS ¹⁴C-dated sediment cores from two sites of tropical upwelling located in climatically-sensitive regions, the Cariaco Basin (Venezuela) and the Arabian Sea. The Cariaco…
In this study analyses of faunal remains are employed to investigate environmental, economic, social, and ideological factors associated with the emergence of a large aggregated Pueblo town in southwestern Colorado, during the Pueblo III period (ca., A.D. 1100–1300). Detailed sp…
I examine the hypothesis that environmental changes associated with the last deglaciation led to the adoption of more diverse and intensive subsistence strategies by Paleolithic hunter-gatherers in southeastern Europe. The rapid climatic warming of the Bolling/Allerod interstadi…
Novel molecular isotope proxies measured in bivalve tissues represent a wide range of approaches for tracing ecological and climatological change through time and space. In comparison to other oceanographic data used to reconstruct modern and past biogeochemical cycles (e.g., ma…
Competition is expected to be important among large (> 7kg) predatory mammals. Prey are difficult to capture, and carcass theft is a lucrative alternative to hunting. Violent interactions over carcasses occur frequently and can result in serious injury. Moreover, adults of small…
The fluvial sediments of the Chinji Formation, Siwalik Group, northern Pakistan, preserve a Middle Miocene vertebrate fossil assemblage that includes hominoids of the genus Sivapithecus. This study provides a chronology for Sivapithecus using geomagnetic reversal stratigraphy an…
The relationship of the \delta¹³C and \delta¹⁸O content of Holocene soil carbonates to variations in climate, plant cover, parent material, and soil depth was examined along several elevation transects in the southern Great Basin. \delta¹³C of pedogenic carbonate in three differ…
The stratigraphy of two facies within the Lower Fars Formation (Miocene) of northern Iraq is redescribed: a basin-centre facies represented by three sections near Fathah, Sheikh Ibrahim and Butma, and a basin-margin facies represented by a section near Shaqlawa. Two members are …
In the northwest Arabian Sea, Ekman transport driven by the southwest-monsoon winds upwells cool, nutrient-rich waters along the coast of Oman. Variations in upwelling are recorded in plankton fossils (foraminifers) and other sediments off Oman, forming a marine-geologic record …
Quaternary climates of the Middle East were investigated by reevaluating previous data and by analyzing pollen in radiocarbon-dated sediments. For comparison, assemblages of modern pollen were obtained from desert regions. Chenopodiaceae and Plantago pollen is high in surface sa…
This thesis reports on the analysis of seed macroremain samples dating to the Late Chalcolithic and Early Bronze Age from Jerablus Tahtani located in present day northern Syria. Detailed numerical and statistical analyses were used to evaluate the relative importance of crop spe…
The Tertiary fossil record of Africa has offered several important primate species relevant to understanding crucial moments in primate evolution. Regrettably, the origin of apes has not been one of them. The reason for this was a large temporal gap of African fossil mammals tha…
The 140 m Dababaiya Corehole (DBQ), drilled in the Dababiya Quarry about 35 km south of Luxor, Upper Nile Valley, Egypt, spans the stratigraphic interval from upper Campanian/lower Maastrichtian (the Globotruncana aegyptiaca Zone) to the lower Eocene. This study is devoted to an…
Historical records suggest that the coastlines of the British Virgin Islands (BVI) and the Sultanate of Oman have been subjected to catastrophic storm and tsunami events throughout recorded history. In 1945, a 7.8 magnitude earthquake ∼100 km south of Karachi, Pakistan generated…
Organic matter dynamics were investigated in the surface peat layer (acrotelm) in study sites traversing three raised ombrotrophic peat deposits, containing up to 3, 6 and 12m, respectively, of peat located on the east coast of Sumatra, Indonesia. The three deposits were uniform…
The Pliocene is an epoch of climatic transition between the warm Miocene and the cool Pleistocene. This climatic transition may have played a critical role in the evolution of many groups of African mammals, and perhaps in the emergence of the genus Homo and the robust australop…
Long-chain n -alkanes are extensively utilized terrestrial plant biomarkers that serve as paleoenvironment and paleoclimate proxy records. However, robust proxy interpretations require robust calibrations, and a major goal of this work is to ground-truth the interpretative frame…
